Examples

After the acrosome reaction, the sperm is believed to remain bound to the zona pellucida through exposed ZP2 receptors. Source: Internet

The receptor galactosyltransferase (GalT) binds to the N-acetylglucosamine residues on the ZP3 and is important for binding with the sperm and activating the acrosome reaction. Source: Internet

There is some evidence that this binding is what triggers the acrosome to release the enzymes that allow the sperm to fuse with the egg. Source: Internet

This involves releasing the contents of the acrosome, which disperse, and the exposure of enzymes attached to the inner acrosomal membrane of the sperm. Source: Internet
